ADM4073HWRJZ-REEL7 from Analog Devices, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Chip ground pin; the ground path is not interrupted, so the device suits battery-powered systems. |
| 2 | GND | power_in | Chip ground pin, connected in parallel with pin 1 to the system ground. |
| 3 | VCC | power_in | Chip power supply, operating range 3 V to 28 V, requiring a 0.1 μF capacitor to ground. |
| 4 | RS+ | input | Power-side connection to the external sense resistor, with a common-mode input range of 2 V to 28 V. |
| 5 | RS− | input | Load-side connection to the external sense resistor, with a full-scale sense voltage of 150 mV maximum across RS+ and RS−. |
| 6 | OUT | output | Voltage output proportional to VSENSE with an output impedance of approximately 12 kΩ, so it should be loaded only by a high-impedance input. |
